High Alumina Bricks,their typical properties include high refractoriness, crushing strenght, density, abrasion resistence and with increased resistence to molten metals, slags, glass and other chemici impacts. They are used to walls, rous and extremely stress parts of metalurgy aggregates (hot blast stoves, blast pipes, gorn of blast furnaces, torpedo ladles and pouring ladles for raw metal, casting ladles), shaft and rotary furnaces for firing lime and cement, linings of tunnel fonace of firing ceramics, turner blocks and ceramics burners' endings.
